Microbiological degradation of Fuel Oil: Evaluation of Changes in Fractional Composition by Analysis of Fourier-Transform Infrared Spectra

摘要

A rapid method for assessing changes in the fractional composition of fuel oil caused by its biodegradation by various microorganisms in liquid medium was designed. This method is based on a modified procedure of regression of principal components of Fourier-transform infrared spectra of fuel oil samples before and after treatment with microorganisms. The spectra of initial fuel oil and its fractions were compared. The fractions were obtained by liquid column chromatography. This method was used for selecting groups of microorganisms sharing similar patterns of fuel oil degradation.
